Rated 1 out of 5 by Waste of money This flux is too thick and when sodlering it does not flux the solder very well. I have now gone back to using powerflow and joints are perfect. This was a HUGE waste of money and time. Avoid and use Powerflow instead! 29 Sep 2015
Rated 3 out of 5 by Flux Very thick and not the easiest to apply, I only did I couple of joints before I got bored of it, overall it's ok but not brilliant in my opinion, I use La-co instead which I find much better, I wouldn't buy this again... 3 May 2014
Rated 4 out of 5 by no green rust though! Yes its thick, much thicker than La-Co but its the only one I've used which is heat activated, which means that if you get some on copper or don't wipe the joint it don't cause ver-de-gris, most of the rest will eventually cause pipe rot unless you clean thoroughly. 25 Feb 2013
Rated 2 out of 5 by dont bother dont bother. buy powerflow or la co flux, this stuff takes longer to brush on as its very thick. 14 Nov 2010
